FLUSH-VALVE.

v Specification of Letters Patent.

Patented May 8, 1917.

Application led June 9, 1916. Serial No. 102,623.

To @ZZ 'whom t may concern.'

Be it known that l, WILLIAM H. SoHUL'rii, a citizen of the UnitedStates, residing at Trenton, county of Mercer, and State of New Jersey,have invented certain new and.

useful Improvements in Flush-Valves, fully described and represented inthe following specification and the accompanying drawings, forming apart of the same.

This invention relates to improvements in Hush tanks to be used inconnection with water-closets, urinals, &c., and has for its object toprovide a device of this character, the parts of which are few innumber, simple in construction, adapted to move as a single unit, inwhich the after flow or refill is secured by the slow closing of themain valve, and which may easily be regulated to meet such requirementsas may be imposed upon them.

ln the accompanying drawing forming'a part of this specification, thereis shown for the purpose of illustration, a flush tank of the preferredform embodying all the features of the invention, and this flush tankwill now be described in detail, and the features forming the inventionthen specically pointed out in the claims.

In the drawing is shown a central vertical section through the flushtank, showing that portion of the tank containing the Hush valve withthe operating parts partly in section.

Referring to the drawing, 5 is the flush tank supplied with a po-rt 6 toadmit the discharge connection 7 provided with a discharge valve seat 8,and a portion 9 extending sidewise for connection with the overflow pipe10. The discharge valve 1, weighted by weight 2, is seated on valve seatS and provided with a downwardly extending valve stem 11 guided byspider 12 mounted within the discharge connection 7. Connected to thetop of valve 1, is a lift rod 18 running through bracket 14, shown asadjustably secured to overflow pipe 10 by set screw 23, and then atright angles by arm 13 having a downwardly bent end connected to float15 operating within float tank 16, supported by bracket 17 adjustablysecured to overflow pipe 10 by set screw 24. The iioat tank 16 isprovided with an inlet and an outlet passage 3 provided with ports 4controlled by the regulating screw 25, so that the rate of flow from thelioat tank 16 may be thus controlled. To an eye 18, formed in rod 13above the valve, is attached a connecting rod 19, to whichin turn isjoined a lever 20, pivoted at 21 and provided with the usual pull-chain22.

The operation of the construction is as follows:

When the tank 5 is full, the upward lift of the float 15 tends to raisethe valve 1 against the weight 2, but owing to the pressure of the waterin the tank, which is pressing the valve downward against atmosphericpressure below the valve, this tendency is not suilicient to raise thevalve. l/Vhen the valve 1 is raised to open the discharge, by a downwardpull upon the chain 22, the pressure above and below the valve 1 isequalized suiiiciently so that the float 15 holds the valve 1 open afterthe hand-pull has been released. rihe valve is held open in this manneruntil the water in the iioat tank 1'6 has run out through passage 3 andports 4 suliiciently, so that the weight of the float 15 in combinationwith the weight 2 closes the flush valve 1, the time of the flush flowand refill of the closet bowl being determined by the adjustment of theregulating screw 25. The valve 1 being in closed position, the tank islled again by an inlet pipe and valve of the usual kind, not shown inthe drawing, and this water flows through ports 4 and passage 3 into theioat tank 16 in order to refill the latter, whereupon the constructionis ready for flushing.

It is understood that applicant does not limit himself to the specificconstruction shown in the drawing, as the float may be' connected invarious positions to the valve without departing from the invention asdelined by the claims.

What is claimed is:

1. A. flushing apparatus having a flush tank and a flush valve, afloatconnected to said valve which by rising tends to open the valve and actsto hold the valve open during the flushing, and a float tank for saidioat having the flow of water therefrom controlled to secure a slowclosing of the iush valve.

2. A flushing apparatus having a flush tank and flush valve, a iioatconnected to said valve which by rising tends to open the flush valve, afloat tank and means for controlling the discharge from said float tankto regulate the length of the flow.

3. In a flushing apparatus, the combination with a flush tank, of aflush valve, a float connected to said flush Valve which by rising tendsto open the flush Valve,l a float tank within which said float operates,a discharge passage for said float tank, said passage having portsconnecting with the ush tank, and a regulating Valve adapted to controlthe rate of flow through said passage and ports.

4. In a flushing apparatus, the combination with a flush tank, of a lushvalve, a

float connected to said flush valve, a float tank within which saidfloat operates, said float in rising tending to open the valve and inlowering tending to slowly close said flush Valve, and means forcontrolling the discharge of water from said float tank to secure a slowrefill flow after the flush.

In testimony whereof, I have hereunto set my hand.

WILLIAM I-I. SCHULTE.
